Firstly, lets clear up some of the techie questions.

The various channels from (the two) stages would have been split probably 4 ways, One to the FOH desk (Hall PA) One to the stage monitor board, another to the TV Scanner Along with their presentation se-up, and one to Radio 3 truck, witch normally lives outside door 11, along with Verities permanent BBC box in the Loggia.

The 4 mixes obviously are for different purposes.
As far as TV is concerned, the mix can be somewhat weird to the listener without the vision, as the guy doing it is following the vision mix to some extent, also adding more audience FX when the shot is of the crowd.

Normally works very well with an orchestra, where you know when the solo's are going to happen (After all you've got a score to look at)

But with Bellowhead, who almost certainly don't play from a score!! It's all a bit seat of the pants stuff.

Hence the different radio mix, which doesn't have to bother with the pictures, and can therefore concentrate purely on the Audio, therefore being more listenable.

I video'd the gig via Freeview, and Recorded the R3 via DAB.
Having listened back to both they are obviously differnt. Proved by the fact that Bellas first intro was fine on R3 but missing on TV!!

Please believe me and I know, because I've done it. It's not easy to rig circuits to the middle of the Arena. It involves crawling under the floor, Hard hat area!!

As for transmission paths. Now that we are in the digital world. It takes a finite time to do all the number crunching. The nearest to a live TX would have been R3 on FM, After that depending on where you live, Freeview and DAB could be anything up to half to a second out.

Hence the reason that simulcasts that used to be so popular during Proms in the 70's (Vision on TV, Sound on R3) are really unworkable nowadays.

Hope this clears some of the Tech stuff up.

Considering the relative complexity of the various rigs, and the fact that the crew only had 3 hours to turn the whole place around after the rather large afternoon Prom. I thought it went reasonably well. (Sound of doffing caps at this point)

As for the artists......

Will get back after some tea!
